IMPROVEMENT IN LAMP-BURNERS.

Specification forming part of Letters Patent No. 203,342, dated May 7,1878; application filed February 1, 1878. v

RICHS and CHARLES REISTLE, of Brooklyn;

in the county of Kings and State of New York, have invented anImprovement in Burners for Illuminating and Heating Purposes, of whichthe following is a specification:

We make use of two flat wicks with an airspace between them, and aroundand between said wicks there is a case, by means of which more or lessof the wick is exposed when either the case or the wick tubes are raisedor lowered. By this means theheight of the flame is regulated. Theamount of air admitted between the wicks is also regulated, ,accordingto the height of the flame, by cut-off plates moved up and down with themoving parts. Swinging wick-covers are applied to cover the upper end ofthe wicks and prevent the escape of vapors when the lamp isextinguished.

For heating purposes these pairs of flat wicks are grouped together, soas to be simultaneously operated in increasing or diminish ing theiiame.

In the drawing, Figure 1 is a vertical section of the burner complete.Fig. 2 is a plan of the same with the deilector removed, and Fig. 3 is aperspective view of the wick-tubes, partially in section.

The wick-tubes a and b are connected together by the eut-oft' plates c,so that there is an air-space between them, and these wicktubes areplaced within the case d that surrounds them. There is also a casebetween the wick-tubes, as at e, and the air passes through that caseinto the space between the two iiames that rise from the tops of thewick-tubes.

If the wick-tubes are raised or lowered-within the case, or the caseraised or lowered around the wick-tubes, the wick will be exposed more'or less, and the height of the flame regulated.

We have shown the case stationary and the wick-tubes movable by means ofthe pinion f, having teeth or points that enter holes in the side of thewick-tubes; and this pinion is turned by a shaft and button-head, g.

We have represented the pair of wick-tubes as in a burner having theOraminous air-disltlibuter h, chimney-rest 7c, and cone or deiiector l.These parts, however, may be varied according tothe character of theburner, and in cases where the pairs of wicks are used for heatingpurposes the chimneyholder will be .dispensed with, and usually severalpairs of wicks will be raised and lowered simultaneously.

The inner faces of the wick-tubes are removed, as at 3, so as to exposethe adjacent sides. This allows for the upper ends of the wicks beinglevel with the tops of the wicktubes, the vapors passing off from thesides of the wicks, as well as the tops; and we make use of mineralwicks formed of suitable noncombustible material, such as asbestus orother .of mineral wool sufficient to prevent the heat charring thecotton wick m, which latter extends down into the oil in thelamp-reservoir.

There are spring-teeth 5 cut in the metal of the wick-tubes at the innersurfaces thereof, which teeth are bent inwardly and stand upwardly, andhold the cotton wick so that it cannot fall away from the packing ofmineral wool. In order to close the wick-tubes and prevent the' escapeof vapors when the lamp is extinguished, we make use of the cap-plates supon vertical arms t, that are pivoted to the cross bearingfbars o insuch a position that the caps s can be swung over the tops of thewick-tubes when the said tubes are turned down to their lowest pointwithin the case; and in order to move such caps, there are camfingers 6upon the outer surfaces of the wicktubes, to act against the projectionsat the lower ends of the arms t and swing the capplates either upon theupper ends of said wick tubes as the latter are moved downwardly, or

to remove said caps from the wick when the wick-tube is raised.

The arms t of the cap-plates lie against the stops 7 7 when not in use,as seen in Fig. 1.

The plates c, that unite the two tubes, act to lessen the space for theair admitted between the wicks as said wicks are moved down wardlybecause the distance between their lowei` edges and the shell of theburner is lessened.

We are aware that two ordinary wick-tubes havebeen used with anair-space between them, and with wick-raising pnions. A sin gleflameslot in the delector has also been used with the double wicks. Amovable case has been used with a single wick-tube and mineral wick, andwith an Argand wick and mineral ring. The tube has been raised orlowered by a pinion. By our improvement the two flat mineral wicks areexposed more o'r less above the in-. terior case e to regulate theflame, and the air passes directly into the llames as they burn fromthese mineral wicks.

We claim as our invention- 1. The combination, with the two wick-tubes,of a surrounding-case, d, and a case, e, between the two wick-tubes, andmeans for raising and lowering the wick-tubes relatively to the case,substantially as set forth.

2. The combination, in a burner, of two wicktubes having an intermediateair-space, and their inner sides removed near the upper ends, the casee, two non-combustible mineral wicks,

and two cotton or supply wicks, substantially C. F. A. HINRICHS. CHS.REISTLE.
